VALVE.

Specification of Letters Patent.

Patented Jan. 9, 1917.

Application filed September 15, 1915, Serial No. 50,850. Renewed August 2, 1916. Serial No. 112,840.

To all whom it may concern:

Be it known that I, BINGHAM S. PRICE, a citizen of the United States, residing at Rawlins, in the county of Carbon and State of lVyoming, have invented certain new and useful Improvements in Valves, of which the following is a specification, reference being had to theaccompanying drawings.

This invention relates to certain improvements in valves and has relation more particularly to a valve of this general character especially designed and adapted for use in connection with a flushing tank or the like and an object of the invention is to provide a novel and improved valve which may be operated with convenience and facility.

Furthermore, it is an object of the invention to provide a novel and improved valve of this general character which is selfdraining. 7

It is also an object of the invention to provide a noveland improved valve including a valve member capable of limitedmove: ment independently of its operatingmeans and which may be positively locked to its operating means so as to be incapable of operation independently of said operating means. 7

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved valve whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter .more fully set forth.

The novel features of the invention will be carefully defined in the appended claims.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a view partly in elevation and partly in section illustrating a valve constructed in accordance with an embodiment of my invention, the same being adjusted to positively operate. Fig.2isasecti0nal view taken substantially on the line 22 with the supply pipe in plan illustrating the valve as herein embodied capable of ordinary operation for the purpose of drainage. Fig. 3 is an enlarged sectional view taken through a valve constructed in accordance with a further embodiment of my invention. Fig. 4 is an enlarged fragmentary view in section of the valve member as disclosed in Fig. 3. Fig. 5 is a sectional view taken through a further form of my improved valve. Fig. 6 is a sectional view taken substantially on the line 6-6 of Fig. 5; and Fig. 7 is a sectional view taken through a still further embodiment of my invention.

As disclosed in the accompanying drawings, 1 denotes a supply pipe of any ordinary or preferred construction and having one extremity terminating in the ground connection 2, adapted to project within the bore of the nipple 3 of'the valve casing 4. As herein embodied, the ground connection 2 is maintained in operative assemblage through the union nut 5, rotatably supported by the pipe 1 and adapted to have threaded connection with the nipple 3 in a well known manner. It is to be particularly noted that the extremity of the pipe 1 disposed within the nipple 3 is provided with a plurality of slots or recesses 6, disposed entirely through the Wall of the pipe and in communication with the bore thereof for a purpose to be hereinafter set forth.

As herein embodied, the valve casing 4 is provided with a chamber 7 having communication with the bore of the nipple 3 through a restricted opening 8, and the outer marginal portion of the opening 8 is surrounded by the substantially conical valve seat 9 with which the substantially conical valve 10 is adapted to coact.

As herein disclosed, the valve 10 is provided with an extension 11 which is disposed through the tubular operating member 12, said operating member 12 being threaded through the casing 41 lengthwise thereof and having its inner extremity reduced as at 1%, and adapted to project through the restricted opening 8, the diameter of said reduced portion 14 being materially less than the diameter of the opening 8 so that no interference will be offered to the flow of the fluid through said opening into the chamber 7 when the member 12 has been so adjusted as to unseat the valve 10.

The stem 11 is preferably hollow and is of a length to project beyond the outer end of the operating member 12 and said extended portion of the stem 11 has in threaded engagement therewith the controlling member 15 herein disclosed as a conventional winged nut. The inner extremity of the stem 11 immediately adjacent the valve 10 is provided with an opening 16 in communication with the bore of said stem, and it is to be particularly observed that the outer end of the stem 11 is open so that when the flow through the supply pipe'l is cut off, the flow of the water therein will result in an adjustment of a movement of the valve 10 into an open position, said adjustment being effected by the suction created by the falling water and it will be perceived that an effective drainage of the supply pipe will be assured, when the stop cock generally interposed in the supply pipe is closed in view of the fact that air will be permitted to pass through the stem 11 past the valve 10 and into the supply pipe 1 through the upper end thereof. By providing the extremity of the supply pipe 1 in connection with the nipple 3 with the slots 6, it will be noted that air will be permitted to enter within the pipe 1 in the event that the valve 10 be drawn into contact with the end of the pipe 1 within the nipple 3. It will be understood that the supply pipe is in communication therewith at a point above the stop cock and discharge vent as is generally employed, and through which the water within the supply pipe above the stop valve discharges when the valve 10 is in an open position.

It will be observed that upon proper manipulation of the controlling member 15, the valve 10 may be adjustably clamped against the inner end of the operating member 12 and that upon reverse adjustment of the controlling member 15-tl1e valve 10 may be permitted to have a predetermined extent of movement independently of the operating member 12 and vice versa.

The operating member 12 also extends exteriorly of the casing 4 and to its outer end has operatively engaged therewith the rod 17 to which is affixed the float 18 of any conventional form. By this arrangement it is thought to be obvious that as the water within the tank drops the leverage of the rod 17 will impart suflicient rotary movement to the member 12 as to cause the stem to move inwardly andthus'unseat the valve 10 and as the water within the tank rises the member 12 will be moved in an opposite direction whereupon the pressure of the water within the pipe 1 will cause the valve 10 to become seated immediately upon the complete retraction of the reduced portion 14 of the member 12 through the restricted opening 8. It will be appreciated that by having the valve 10 positively held against the inner end of the member 12 by the controlling member 15 that the valve 10 will be seated wholly under the influence of the operating member 12.

As herein embodied, the casing 4 has in communication with the chamber 7 the depending discharge pipe 19, the discharge end of which being restricted as at 20 so as to force a portion of the water entering within the chamber 7 when the valve 10 is open, through the overflow pipe 21 also in communication with the chamber 7 and serving for a purpose which is believed to be selfevident.

In practice I find it of advantage to have the extremity of the supply pipe 1 operatively engaged with the nipple 3 offset as.

indicated at 22 which in practice allows additional space for adjusting the stem 11 and the valve 10 under the influence of the controlling member 15.

It will be appreciated that in the successful operation of my device it is not essential that p the valve seat 9 be conical and the valve 10 correspondingly formed. As disclosed in Fig. 8, the valve seat 9 is afforded by an annular flange and the valve 10 includes the compressible body 23 adapted to engage said seat 9 Furthermore, it is not necessary in the successful operation of my device to have the stem of the valve hollow as said stem may be longitudinally grooved or fluted as indicated at 11 in Fig. 5.

My invention may also be employed with facility by having the solid stem 11 of the valve 10 suitably connected as disclosed in Fig. 7 and the valve 10 may be of a disk type coacting with a flat valve seat 9 the opposed faces of the seat 9 and the valve 1O preferably being ground.

From the foregoing description, it is thought that a valve constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

It is also to be stated that it is desired that the end of the reduced extremity 14; and the inner face of the valve member 10 be ground to prevent any leakage through the stem 11 when the valve member 12 is clamped in contact with the end of the reduced extremity 14.

I claimi 1. A valve comprising a casing provided with a valve seat, a valve coacting with said seat, a rotatable operating member for the valve, a. stem carried by the valve and disposed through the operating member from end to end, means adjustably carried by the stem of the valve and coacting with the operating member for imparting endwise movement to the stem, and means for rotating the operating member.

2. A valve comprising a casing provided 1 with a valve seat, a valve coaoting with said seat, a rotatable operating member for the valve, a stem carried by the valve and disposed through the operating member, means adjustably carried by the stem of the valve and coacting with the operating member for imparting endwise movement to the stem, and means for rotating the operating member, said stem of the valve being hollow and having a port in its end adjacent the valve.

3. In combination with a supply pipe, of a casing secured upon the end thereof, said end of the supply pipe being provided with slots disposed through the wall thereof, a valve for controlling the flow through the casing an operating member rotatably supported within the casing, a stem carried by the valve and disposed through the operating member and capable of movement independently thereof, and a means carried by the stem and coacting with the operating member for imparting endwise movement to the-stem.

l. A valve of the character described comprising a casing, a Valve therein for controlling the flow therethrough, an operating member for the valve, a stem carried by the valve and disposed through the operating member, said stem being provided with a channel, and means carried by the stem 00- acting with the operating member for controlling the position of the valve relatively to the operating member.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
